The word “quantum” has been quite a sensitive word, especially when paired with the world “physics”. Apparently everything explodes into the midst of air and gone when they both joint together. However, quantum dots have been a real deal, and it’s as real as it gets. Samsung has demonstrated a four-inch quantum dot display with full color.

Quantum dots are nanocrystals that emit light when they get excited, perhaps on Christmas morning or when waiting for the list of school cancellations on a snowy morn. The size of the crystal dictates the wavelength of light emitted, and by laying precise grids of different sized crystals Samsung creates RGB pixels of the sort needed to make a display. Pixels can be applied directly to glass or to a flexible surface, and in theory they’ll be far more efficient than an LCD while brighter and longer-lasting than OLED.

Of course, this is a super early stage prototype, as no benchmarks have been tested yet. As usual, the Koreans lead in technology and the US commercialize those 5 years later. Like a professor once said, go to any Korean lab right now, and what they’re testing most probably will be what we’re going to use 5 years later.
